GS4A0275R0JFT Description

The GS4A0275R0JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 4-resistor isolated network features a 75Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance across all elements. Encased in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology delivers excellent stability, with a low temperature coefficient of ±50ppm/°C, making it suitable for temperature-sensitive circuits. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates reliably across a wide temperature range (-70°C to +125°C).
